Benzhydryl bromide, 90+%
CAS: 776-74-9 | C13H11Br | 247.135 g/mol
Supplier: Thermo Scientific Chemicals L0221114
Description
Benzhydryl bromide is a halogenated building block. Benzhydryl group was preferred to the commoner benzyl to protect 2-nitrophenol in the Bartoli (vinyl Grignard) synthesis of 7-hydroxyindole. Protection was by reaction with the phenol in the presence of potassium carbonate in acetone; deprotection of the indole was by hydrogenolysis.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
